HOT-AIR DEFLECTOR AND ousT-coLLEoi'oh i=oR RAmAfoRs.

1'0 111/ whom it 111111;; concern:

Be it known that I, CHRISTIAN E. SCHAFER, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hot- Air Deflectors and Dust-Collectors for Radiators; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and'use the same.

This invention relates to an improved hotair deflector and dust-collector for radiators.

One object of this invention is to construct a combined deflector and d est-collector of the character indicated which will deflect the hot air from over the radiator forwardly and arrest and collect dust anddirt carried by the Another object is to construct the air-deflectin hood of the device in three sections, with the central section overlapping the adjacent ends of the end sections, so that the latter can be used in connection with any radiator, and the central section employed will vary in length with the size of the radiator in connection with which my improved device is to be used.

Another object of this invention is to provide a combined air-deflector and dust-collectorwhich is simple and durable in construction and readily applied to and removed from the radiator and which can be conven-' iently cleaned.

With these objects in view and to the end of realizing other advantages hereinafter appearing this invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front side elevationof the upper portion of a radiator provided with a combined hot-air deflector and dust-collector embodying my invention, and portions are broken away in this figure to more clearly show the construction. Fig. 2 is a vertical section on line 2 2,

Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a vertical longitudinal section taken through the centralportion. of the air-deflecting hood looking rearwardly. Fig. 4 is a horizontal section in detail on line 4 4, Fig. 1, and drawn on a larger scale than Specification of Letters iatent.

the upper portion of the uprlght heater forming sections of a radiator.

My improved combined hot-air deflector A and dust-collector comprises an air-deflecting hood which is helmet-shaped and preferably composed of two end sections B and B and a central section b. Each hood-section is provided with a top 6, which is spaced a suitable distance above the radiator. The said to is provided at the rear of the radiator wit 1 a depending portion 7, which forms the back of the hood. The space within the hood has two end walls 8, formed at opposite ends, respectively, of the hood on the outer end of opposite end sections B, respectivelythat is, each end section B of the hood is provided at its outer end with an end wall 8, depending from the top of the said section. The central hood-section l) is large enough longitudinally of the hood to render it capable of overlapping the outer sides of the end sections B of the hood. The hood is supported from the radiator in any approved manner. Preferably each hood-section is provided at the under side of its top 6 with a slideway 10, which is arranged longltudinall of the hood and formed by plates D, whic 1 are suitably secured to and spaced transversely of the said hood-section. 1

The slideway 10 is engaged by a slide which is shiftable or adjustable endwise of the slideway 10, and conse uently longitudinally of the hood, which slide is formed by a pair of plates d, engaging the said slidewa and arranged end to end longitudinally of the slideway. Each plate is provided at'its inner end with a depending arm 12. The arms 12 of each pair of plates (Z are suitably secured together. The slideway-forming plates D are arranged far enough apart forwardly and rearwardly of the hood to accommodate the location of the arms 12 between the said plates. Each arm 12 terminates in a spring clam ing member 13, and the clamping mem ers 13 of the said plates are adapted to straddle and clamp the upper end of one of the radiator-sections A. In other words, the

hood is provided with spring-clamps adapted to reinovably attach the hood to the upper portions of the sections A of the radiator, while the said clamps are adjustablelongitudinally of the hood to accommodate variations or irregularities in the size or configuration of the radiator-sections.

I prefer to 1provide the central hood-section I), as wel as the end hood-sections B, with means for removably attaching the hood to the radiator; but obviously the said central section, overlapping the outer sides of the end hood-sectionsfls supported upon the latter. However, the provision of means employed in directly supporting the central hood-section from the radiator is important to positively prevent sagging of the top of the said hood-section.

My improved hot-air deflector and dustcollector is shown provided at the forward side of the air-space formed between the end walls 8 of the hood with a forwardly-facing wire screen 6, having fine meshes. A stiff or self-sustaining screen e is preferably employed. The screen e is supported, preferably, from a forwardly-bulging foraminated or perforated sheet-metal late G, which extends between the end wal s 8 at the front of the hood.

The space formed'betw-een the rear or inner side of the plate G and the forward or outer side of the screen e forms a chamber for collecting any dust or dirt which may pass.

through the screen. The outward curvature or bulge of the plate G enlarges the aggregate air capacity of the perforations formed in the plate. The screen-holding plate G is supported from the hood-sections B and b in any approved manner. Preferably the three sections of the hood are connected together at the lower ends of their backs 7 through the medium of a rod f, which is embraced by cylindrical bends 14, formed on the lower ends of the said backsthat is, the backs 7 of the hood-sections, or, at least, portions of the said backs, are bent in under and around a rodf, as shown very clearly in Figs. 2 and 5. The rod f and the embracing-bends 14 hold the hood-sections at the lower ends of their backs 7 properly assembled and reinforce the hood.

A tube It is arranged at the forward end of the tops '6 of the hood-sections and extends longitudinally of the hood, and the tops 6 of the end hood-sections B are bent, as. at 15, over and forwardly around and in under the said tube. The top 6 of the central hoodsection b terminates at its forward end in a bend 16, which extends over and forwardly around the bends 15 of the hood-sections B. The tube It and the bends 15 and 16 of the to s of the hood-sections are instrumental in ho lding the said hood-sections properly as sembled and reinforce the hood. The bend 15 of each end hood-section B at the bottom of the tube It projects rearwardly in a horizontal plane. as at 17, and the plate or screenholderG at its upper edge is provided with hooks 18, overlapping the upper side of and removably mounted on the said rearwardlyproject-ing portions 17 of the bends 15 of the hood-sections B, as shown very clearly in Fig. 6. The plate or screen-holder G is therefore removably supported at the top from the hood-sections. The hooks 18 are rounded, as shown in Fig. 6, so as to accommodate the swingin of the plate or screenholder G forwardl but the latter can be readily detached from the hood by moving it rearwardly to disengage its hooks 18 from theengaging portions of the hood-sections B.

The plate or screen-holder G is bent at its lower end, as required, to form a channel-bar g, arranged to form a pocket which is .open at the top, as shownin Fig. 2, and extends longitudinally and from end to end of the screen-holder. The member g affords a bottom bearing to the screen e, which extends longitudinally of the hood into close proximity to both end walls 8 and is held in position at the top by hooks or projecting members 20, which are formed on the plate G and extend over the upper edge of the screen, as shown very clearly in Fig. 6, and overlap the rear or inner side of the screen. Obviously the back or inner side of the screen is rendered readily accessible to be wiped upon swinging the screen-holder forwardly or on twardly, and upon detaching and removing the screen-holder from the hood the screen can be slid endwise and withdrawn from the screen-holder to be thoroughly cleaned, if necessary.

Means for locking the screen-h olderG to the end walls 8 is provided, and comprises, preferably, the following: Each end wall 8 is provided at the adjacent end of the screen-supporting member g of the screen-holder'with a ateral perforation 23, as shown very" clearly in Fig. 4. A pin K extends loosely through the said perforation into the space formed within the member 9 at the forward side of the screen 9, which pin is provided at its outer end with a head k, arranged to abut against the outer surface of the said end wall. A pin Z (see Fig. 4) engages a hole K, formed in and arranged transversely of the aforesaid pin K and extends through a hole 24, formed in the screen-supporting member 9 of the screen-holder G. It will be observed, therefore, that the pins 1 and K effectually hold the screen-holder to the end walls 8 of the hood, but that the screen-holder is rendered free to be swung forwardly and removed from the hood upon withdrawing the pins K after a withdrawal of the pins Z.
